Bug fixes

WCF RIA Services Toolkit (April 2011)

Download available here. Or use the NuGet packages shown below. The Linq To SQL DomainService and the ASP.NET Web Forms controls are only available through the MSI.

This is a new drop of the Toolkit, replacing the December 2010 version. This version of the Toolkit works for both WCF RIA Services SP1 and SP2, and both Silverlight 4 and Silverlight 5. Here is what you’ll find in this new drop:

Works with both SP1 and SP2, providing Silverlight 4 or Silverlight 5 support

Updates to the ViewModel features (such as the DomainCollectionView) to work with 3rd party controls and to fix some bugs and memory leaks

Updates to the T4 Code Generation to allow you to create VB code generators using the T4 approach

Toolkit NuGet Packages

As an alternative to the Toolkit MSI, we are now also publishing NuGet packages for many of the features found in the Toolkit. This allows you to install the package directly into your project without installing the MSI on your machine. For more information about NuGet, check out the official NuGet website. All of our NuGet packages are prefixed with “RIAServices.” and here is what you can find out there today:

RIAServices.jQuery - An early preview of the jQuery client for RIA Services. Provides JavaScript files and updates your JSON endpoint to add a transmitMetadata="true" property that allows your model's metadata to be transmitted with requests. More info here.

I am able to NuGet all the above packages within VS 2010 Ultimate except for the ViewModel and JQuery packages. With ViewModel I get the following first error when executing the install through the Package Manager Console. {MySolution Foldere}\RIAServices.ViewModel.4.1.60411.0\lib\Sl40\Microsoft.Windows.Data.DomainServices.dll could not be found in your workspace, or you do not have permission to access it. This error is followed by many others. Any ideas what is causing this?
